Systems, methods and devices are disclosed for use in electronic guidance systems for surgical navigation. A sensor is provided with an optical sensor and an inclinometer (e.g. accelerometer or other inclination measuring sensor) and communicates measurements of patient inclination to an inter-operative computing unit. A registration device is useful to construct a registration coordinate frame. The direction of gravity may be used to construct the registration coordinate frame such as determined from inclination measurements.

Systems, methods and devices to measure and display inclination and track patient motion during a procedure

Systems and methods are disclosed for use in electronic guidance systems for surgical navigation. A sensor is provided with an optical sensor, to provide optical information, and a measuring sensor, to provide measurements for determining a direction of gravity. The sensor communicates optical information and measurements to an inter-operative computing unit. In an embodiment, the inter-operative computing unit receives first optical information for a registration device and a patient anatomy and a measurement to determine a direction of gravity to perform a registration step. The inter-operative computing unit receives second optical information for the patient anatomy and an object and determines and presents measurements relative to the anatomy. The measurements relative to the anatomy are determined from the second optical information, and in relation to the registration of the anatomy of the patient.

Systems and methods to register patient anatomy or to determine and present measurements relative to patient anatomy

Methods and a kit for a navigated procedure, such as a navigated surgical procedure relate to an optical sensor system such as a sterile optical sensor system. The methods relate to using components of the optical sensor system and a processing unit, for example, performing a navigated procedure using an optical sensor as draped and using the processing unit coupled to the optical sensor. Performing the navigated procedure comprises receiving instructions for the navigated procedure from the processing unit, and using the optical sensor comprises interacting with a button on the optical sensor through the drape to provide input to the processing unit. A kit comprises optical sensor system components and instructions for performing a method.

Methods and kit for a navigated procedure

Systems, methods and a sensor alignment mechanism are disclosed for medical navigational guidance systems. In one example, a system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery includes a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier and a sensor alignment mechanism. The alignment mechanism secures the sensor through the drape in alignment with the window without breaching the sterile barrier and facilitates adjustment of the orientation of the optical sensor. The optical sensor may be aligned to view a surgical site when the alignment mechanism, assembled with the sterile drape and optical sensor, is attached to a bone. The alignment mechanism may be a lockable ball joint and facilitate orientation of the sensor in at least two degrees of freedom. A quick connect mechanism may couple the alignment mechanism to the bone.

Systems and methods to compute a subluxation between two bones

Systems, methods and devices are described herein for performing a navigated surgical procedure involving a patient's anatomy in sterile and non-sterile surgical environments. A camera may be used to determine a registration of the camera coordinate-frame to the patient anatomy or optionally a tracker in relation to the patient anatomy. A drape may be applied to permit use in a sterile surgical environment. The camera may be moved from its original position to enable access to patient anatomy while maintaining a registration of the camera coordinate-frame with the patient anatomy. Alternatively, the camera may be used in a hand-held or head-mounted manner. A visualization of the patient anatomy may be displayed on a computing unit, with visualization reference planes defined by the pose of an instrument or the camera. The visualization may be presented on a display of a computing unit or as part of a head mounted augmented reality system.

A method and apparatus for providing an unsterilized item to a sterile field is disclosed. The item can include a human input device. The sterile field can be in an operating room.

Systems and methods to compute a positional change between two bones

Systems, methods and devices are disclosed for use in electronic guidance systems for surgical navigation. A sensor is provided with an optical sensor and an inclinometer (e.g. accelerometer or other inclination measuring sensor) and communicates measurements of patient inclination to an inter-operative computing unit. The computing unit is configured to determine patient movement (e.g. relative to an initial patient position) and provide inclination measurements graphically via a GUI to represent patient movement during a procedure. The graphic may be selectively displayed. In one example, a bubble level graphic is displayed to indicate patient movement. A direction of the bubble level may utilize a registration coordinate frame of the patient and the current inclination expressed with respect to the anatomical directions of the patient.

Sterile optical sensor system having an adjustment mechanism

Systems, methods and devices are disclosed for use in electronic guidance systems for surgical navigation to determine the relationship between the three-dimensional coordinates of an anatomy of a patient and those of an electronic guidance system. These coordinates are required to assist in the determination of the angles with respect to which components, such as, an acetabular prosthesis, are inserted into a body of the patient. In one such example, during hip replacement surgery, a surgeon receives guidance of how to place an acetabular prosthesis in the body of the patient, specifically in the pelvis.
